Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

The greatest enemy to human potential is your comfort zone

There are no shortcuts to any place worth going.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

We learn more from failure than we do from success.

Success can never happen without the journey (struggle).

The bad news is time flies, the good new is that you're the pilot.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

I think, therefore I am.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Hope might be a good breakfast, but it makes a very poor dinner

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Success is the sum of small repeated efforts, day in and day out.
